Fine-tuning peg for violin and plucked string instruments

Abstract

The invention provides a fine-tuning peg for violin and plucked string instruments. According to the fine-tuning peg for the violin and plucked string instruments,. a planetary gear reducer and a string winding shaft are mounted in a hollow peg body, an input shaft of the planetary gear reducer is connected with a rotary knob, an output shaft is connected with one end of the string winding shaft,the string winding shaft extends out of the peg body, and a string hanging device is mounted on the part, close to the peg body, of a square peg of the string winding shaft. A sleeve pipe is mounted on the part, extending out of the peg body and away from the peg body, of a round peg of the string winding shaft, and the outer side face of the sleeve pipe is a circular conical surface. The tuning peg is mounted on a headstock of an instrument in the using process, a mounting hole matched with the peg body and a through hole allowing the string winding shaft to penetrate through are formed in the headstock, in the mounting state, the sleeve pipe is mounted in the through hole in a penetrating mode, the peg body is mounted on the mounting hole in a penetrating mode, the round peg extends intothe sleeve pipe, and the round peg is in clearance fit with the sleeve pipe. After the tuning peg is mounted well, a string penetrates through the string hanging device and string penetrating holes in the string wind shaft, rapid coarse tuning of the string can be achieved by rotating the peg body manually; and accurate fine tuning of the string can be achieved by rotating the rotary knob, no radial offset is generated in the rotating process of the string winding shaft, and accurate fine tuning is ensured.

Description

technical field [0001] The invention relates to a peg for adjusting the tension of strings, in particular to a fine-tuning peg for violins and plucked instruments. Background technique [0002] The strings on some stringed instruments (such as Erhu, Jinghu, violin, etc.) and plucked instruments (such as pipa, etc.) are tightened and adjusted by the pegs. Yes: It is inconvenient and difficult to control when fine-tuning the string tension and tuning. In order to realize the precise adjustment of the strings, the basic structure of a peg disclosed by the Chinese patent is as follows: a planetary reducer is installed in the rear of a hollow shaft body, a winding shaft is installed in the shaft body, and the input of the planetary reducer The shaft is connected with the knob at the rear end of the shaft body, the output shaft of the planetary reducer is connected with the rear end of the chord shaft, the front end of the chord shaft protrudes from the shaft body, and the shaft ...

AI Technical Summary

Problems solved by technology

The peg can fine-tune the strings, but the disadvantages are: the shaft section protruding from the peg outside the shaft is not ideally supported or matched, and after the string is wound on the peg, it is driven by the knob through the planetary reducer. During the rotation, the winding shaft has a radial offset, which will affect the accuracy of the fine-tuning; every time you tune the string, you need to loosen the nut first, and then tighten the nut after the tuning is completed, which is more troublesome to operate
